They already have a set of people who will be official witnesses. For what I don't know yet, but that sounds like they plan to move it to a court case as the next phase.

Legal system is not like bitcoin. It's very, very slow. Also a lot of people are not witnessing because the SEC has been so secretive about their intentions (not to mention it opens yourself up to all government agencies), so right now effectively the SEC is protecting Pirate since their involvement prohibits other lawyers from collecting: the SEC gets "first dibs" always. THAT is the reason you haven't seen anything serious happen yet on the legal front yet, not because people are sitting on their hands.
